Case 6:18-cv-00055-ADA Document 26 Filed 01/11/19 Page 7 of 13 AFFIRMATIVE DEFENSES Without prejudice to the denials hereinabove set forth in the Answer, without admitting any of RetroLED s allegations not otherwise admitted, and without undertaking any of the burdens imposed by law on RetroLED, PLG asserts the following defenses to RetroLED s Amended Complaint, and expressly reserves the right to allege additional Affirmative Defenses as they become known during this litigation: FAILURE TO STATE A CLAIM The Amended Complaint fails to state a claim upon which relief may be granted. INFRINGEMENT OF THE 835 PATENT RetroLED s Amended Complaint should be dismissed because RetroLED has infringed and continues to infringe, either directly, contributorily, by inducement, jointly, literally, or under the doctrine of equivalents, the claims of the 835 Patent as set forth in PLG s Counterclaims herewith. VALIDITY OF THE 835 PATENT RetroLED s Amended Complaint should be dismissed because the claims of the 835 Patent are valid under Part II of Title 35 of the United States Code, including, but not limited to, 101, 102, 103, and 112. In particular, the claims of the 835 Patent are presumed valid in accordance with 35 U.S.C. 282 and RetroLED has failed to establish clear and convincing evidence that the claims are invalid in view of the prior art references cited in the Amended Complaint. Page 7

Case 6:18-cv-00055-ADA Document 26 Filed 01/11/19 Page 8 of 13 PRINCIPAL LIGHTING GROUP, LLC S COUNTERCLAIMS FOR PATENT INFRINGEMENT AGAINST RETROLED COMPONENTS, LLC Pursuant to Federal Rule of Civil Procedure 13, Defendant/Counter-Plaintiff Principal Lighting Group, LLC ( PLG ) hereby asserts the following counterclaims of patent infringement against Plaintiff/Counter-Defendant RetroLED Components, LLC ( RetroLED ) and avers as follows: A. NATURE AND BASIS OF ACTION 1. This is a civil action for the infringement of United States Patent No. 9,311,835 ( the 835 Patent or the Patent-in-Suit ) under the Patent Laws of the United States 35 U.S.C. 1 et seq. B. PARTIES, JURISDICTION AND VENUE 2. PLG is a Delaware corporation and maintains a place of business at 3490 Venture Drive, San Angelo, Texas 76905. 3. On information and belief based solely on Paragraph 1 of the Amended Complaint as pled by RetroLED, RetroLED is a limited liability company formed under the laws of the State of Texas. RetroLED has its principal place of business at 1515 North Grandview Avenue, Odessa, Texas 79761 within the Western District of Texas. 4. This Court has jurisdiction over the subject matter of this action pursuant to 28 U.S.C. 1331 and 1338 because it arises under the Patent Laws of the United States, United States Code, Title 35. 5. This Court has personal jurisdiction over RetroLED by virtue of the fact that RetroLED is a Texas limited liability company and has submitted to the jurisdiction of this Court by bringing the instant action. 6. Venue in this District is appropriate over these Counterclaims because RetroLED Page 8

Case 6:18-cv-00055-ADA Document 26 Filed 01/11/19 Page 9 of 13 has consented to the propriety of venue in this district by filing its Complaint for Declaratory Judgment in this Court, in response to which these Counterclaims are asserted. 7. RetroLED is subject to this Court s specific and general personal jurisdiction pursuant to due process and/or the Texas Long Arm Statute, due at least to its substantial business in this forum including but not limited to: (i) at least a portion of the infringements alleged herein; and (ii) regularly doing or soliciting business, engaging in other persistent courses of conduct, and/or deriving substantial revenue from goods and services provided to individuals in Texas and in this district. C. RETROLED S INFRINGEMENT OF U.S. PATENT NO. 9,311,835 8. PLG owns, by assignment, the 835 Patent entitled Lighting mount for interiorlighted signage and method of retrofitting a lighted sign. A true and correct copy of the 835 Patent is attached hereto as Exhibit 1. 9. There is an actual and justiciable controversy between the parties arising under the Patent Act, 35 U.S.C. 1, et seq. concerning RetroLED s infringement of one or more claims of the 835 Patent. 10. RetroLED, in violation of 35 U.S.C. 271, has infringed, literally or through the doctrine of equivalents, and continues to infringe the 835 Patent through RetroLED s making, using, selling, and/or offering for sale in the United States, and specifically in this district, light support assemblies that fall within the claims of the 835 Patent. 11. On information and belief, RetroLED has directly infringed at least claim 1 of the 835 Patent under 35 U.S.C. 271(a) by making, using, selling, and/or offering for sale complete light support assemblies incorporating, for example, Rigid end caps (e.g., part nos. EC-T-12 HO and TOREC). Further, for example, RetroLED s website lists a number of different Page 9

Case 6:18-cv-00055-ADA Document 26 Filed 01/11/19 Page 10 of 13 RetroLED end caps which can be combined with RetroLED s [proprietary] Light Stick[s] to form an infringing light support assembly. See http://www.retroledcomponents.com/trinity- 360.html (attached hereto as Exhibit 2). This includes at least the accused Rigid end caps. 12. RetroLED has had actual notice of the 835 Patent and RetroLED s infringing instrumentalities since at least as early as its receipt of PLG s February 12, 2018 letter to RetroLED regarding infringement of the 835 Patent. 13. On information and belief, RetroLED has indirectly infringed at least claim 1 of the 835 Patent under 35 U.S.C. 271(b), literally and/or under the doctrine of equivalents, by actively, knowingly, and intentionally inducing infringement of the 835 Patent by others (e.g., RetroLED s customers, distributors, partners, and/or third parties). In particular, RetroLED s website specifically advertises that its components (including the accused Rigid end caps) enable [customers] to choose LEDs from any manufacturer and build LED Light Sticks in your shop or on-site. See http://www.retroledcomponents.com/modular-components.html (attached hereto as Exhibit 3). RetroLED s end caps can be used and are intended to be used to frictionally engage ends of elongate support members that support a plurality of electric lamp units (e.g., LEDs). See Exhibits 2, 3. Further, RetroLED s end caps have electrically insulative mechanical coupling elements that do not retain electrical conductors along or through the mechanical coupling elements. See Exhibits 2, 3. 14. On information and belief, RetroLED has indirectly infringed at least claim 1 of the 835 Patent under 35 U.S.C. 271(c), based on RetroLED s marketing and sales of, for example, its Rigid end caps. As previously discussed, RetroLED knowingly and intentionally advertises and sells its products to customers with the expectation that customers will use, for example, the Rigid end caps to form light support assemblies covered by at least claim 1 of the Page 10

Case 6:18-cv-00055-ADA Document 26 Filed 01/11/19 Page 11 of 13 835 Patent. As such, RetroLED is liable for contributory infringement under 35 U.S.C. 271(c) of at least claim 1 of the 835 Patent as its end caps are not capable of any substantial noninfringing uses. 15. On information and belief, RetroLED has directly infringed at least claim 1 of the 835 Patent due at minimum to its use of lamp support assemblies as recited in claim 1 of the 835 Patent. See Exhibits 2, 3. 16. On information and belief, RetroLED makes, uses, and sells components or component kits used to make a lamp support assembly as recited in claim 1 of the 835 Patent. RetroLED instructs others to combine the components in a manner to infringe at least claim 1 of the 835 Patent. See Exhibits 2, 3. 17. RetroLED has been aware of the 835 Patent at least since its receipt of PLG s February 12, 2018 letter to RetroLED regarding infringement of the 835 Patent. At least based on that awareness of the 835 Patent, RetroLED s infringement of the 835 Patent is, has been, and continues to be willful and deliberate. 18. On information and belief, RetroLED has continued and will continue to infringe one or more claims of the 835 Patent unless enjoined by this Court. 19. As a direct and proximate result of RetroLED s infringement of the 835 Patent, PLG has been and continues to be damaged in an amount yet to be determined. 20. Unless RetroLED s ongoing infringement is enjoined, PLG will suffer irreparable injury for which there is no adequate remedy at law. 21. This is an exceptional case such that PLG should be entitled to its reasonable attorneys fees and expenses incurred in prosecuting this action and defending any declaratory judgment requests or counterclaims brought by RetroLED.
